In our Questions and Answers column we talked about different approaches to setting up a network firewall. There are a number of tools on Linux distributions and the BSD flavours which can be used to filter network packets. On the Linux side the underlying filters are ipchains, iptables, and nftables. In the BSD communities there are a few different packet filters, including pf, ipfw, and ipf. Which of these do you use on your system?

Cleaning-out-the-cruft asks: According to Wikipedia, iptables superseded ipchains; and the successor of iptables is nftables. However, on CentOS we still find iptables 1.4.21 in CentOS 7.8 and iptables 1.8.2 in CentOS 8.2. So why is iptables still around in modern distribution releases?
DistroWatch answers: I have a few answers to this question. First, when talking specifically about CentOS 7.8, the reason iptables is still in use there is nftables requires version 3.13 of the Linux kernel. The CentOS 7.x series ships with Linux 3.10. This means nftables will not run on CentOS 7.8 and iptables would be the most modern tool in the packet filter series available.
But why does CentOS 8.x, which uses version 4.18 of the kernel, still include iptables? The main reason is probably that iptables still works perfectly well and has been around for two decades. Virtually every Linux system administrator who has been in the work force at some point since the year 2000 will be familiar with iptables, but nftables has only been around for about six years (or one major version of CentOS/RHEL).

After making it hard for users to install the Chromium web browser on their distributions by deciding to drop support for Ubuntu’s Snap universal packages with the Linux Mint 20 release onwards, the Linux Mint developers are now packaging Chromium and distributing it trough the official repos.

The Linux Mint team has arranged to provide its own Chromium package to users who were previously pointed towards Canonical's Snap Store if they wanted to get the popular browser.
"The Chromium browser is now available for both Linux Mint and LMDE," said Mint maintainer Clement Lefebvre, noting that the build process for the application and new package is a lengthy one "which can require more than six hours per build on a fast computer."
